Application filed September 1, 1915. Serial No. 48,398.

To all whom it may concern:

Be it known that I, CLAUDE ELLIS, of Springville, ltrie county, NewYork, United States of America, have invented a \Vindow Screen and SashLocker, a new and useful device for the purpose of locking the lowerwindow-sash of an ordinary window firmly to the ordinary window-screenof commerce and also at the same time looking the upper window-sashfirmlyto its casing.

This device is also torthe purpose of locking an upper window sashfirmly on to the ordinary screen of commerce when put in the upperwindow space and at the same time firmly locking the lower sash to itscasing. When used in either window space the device prevents the raisingand lowering of both windows while the screen is in place and alsoserves to lock the window screen to the window casing.

1 accomplish these ends b the mechanism illustrated in the accompanyingdrawings.

This invention relates to window sash and screen locks or fasteners, andhas for its object to produce a device of this character which is strongand simple in construction,

cheap to manufacture, and which can be used in connection with windowsand window screens of various Kinds and sizes, to hold the window sashesand screens securely against opening.

The device is portable and can be readily and very quickly applied to awindow ordetached therefrom without scarring or 1111111- ing thewood-work in any way.

In the accompanying drawings: Figure 1 is a sectional perspective viewof a window provided with a sash and screen lock constructed inaccordance with this invention,

the screen being. placed beneath the partially raised lower sash andboth sashes and the screen locked in position. Fig. 2 is a sectionalelevation, on a reduced scale, thereof. Fig. 3 is a side elevation,partly in section, on an enlarged scade of the device in lockingposition as applied to an ordinary window. Fig. 4 is a sectional plan ofthe adpistable locking collar. partly in secti n. on the same scale asFig. 3, showing a modification of the device.

6 represents a window of o-dinarv construction having sliding upper andlower sashes 7 and 8 provided with window panes 9 in the usual manner.As shown in Figs. 1 and 2, the lower sash S is raised to admit a Fig. 5is a front ele ation,

by means of a screw or bolt 14:, the ends of which extend intolongitudinal recesses 15 and 16 formed respectively in the lower andupper sections. In the construction shown in Figs. 1 1, the rod sections12 and 13 are made of wood, although they could be made of metal, as inthe device shown in Fig. 5. 17 represents pins which serve to hold theupper end of the bolt securely in place in the recess 16 of the uppersection although, if preferred, any other means of fastening the upperportion of the bolt securely in the recess may be used. The recess 15formed in the lower section 13 has a slightly greater diameter than thatof the bolt so that the section may move vertically in respect thereto,and the lower portion of this recess is enlarged forming a springchamber 18. 19 represents a coil spring en I circling the lower portionof the bolt in the chamber 18, the bolt being provided with a head 20 atthe lower extremity thereof which serves to keep the spring in positionand also prevents the bolt from being removed from the chamber. Thespring is normally compressed between this head 20 and a shoulder 21formed at the upper end of the spring chamber 18. 22 represents an adjusting nut arranged to turn on the screwthreaded porticn of the bolt 14between the two rod sections. The nut is of ordinary ccnstructicn and,in the device shown in Figs. 1-4, is secured in any suitable mannerwithin a short cylinder 23 of wood, metal or any other desired material,which is preterably of the same diameter and external appearance as thered sectirns 12 and 13, and has a central recess of the same diameter asthe recess 17. The spring 20 hclds the upper end of the lower rcdsectirn 13 against the lower end of this cylinder 23. so that when thent 22 is screwed dwvnwardlv on the bolt, the section 13 will be moveddownwardly a corresponding distance relative to the bolt. When the nutis screwed upwardly on the bolt, the lower section 13 is moved upwardlya corresponding distance by the action of the spring. In this way thereis always a tight fit between the top of the lower section 13 and thebottom of the adjusting cylinder 23. represents a collar or bracketmember mounted to slide on the upper section 12 of the device, and

' secured at the upper and lower extremities of the sections 12 and 13respectively, to

prevent injury to the woodwork of the window casing and sashes when thedevice is applied thereto, although either or both of these disks may beomitted.

In the modified construction, shown in Fig. 5, the rod sections 30 and31 are con structed of metal. In this construction the upper section 30is provided in its lower end with a screwthreaded cavity 32 into whichthe bolt 33 is screwed. This provides an additional means of adjustmentof the device in addition to the adjusting nut 34: which corresponds tothe nut 22 used in the wooden construction. Except for this differenceand the fact that the metallic rods 30 and 31 are preferably made of asmaller diameter than the sections 12 and 13 of the wooden device, thismodified device. is the same in construction and operates on the sameprinciple as the other construction.

In operation the device can be used in connection with windowsand'screens of various sizes. As shown, in Fig. 1 of the.

drawings, the lower sash 8 of the window is raised and the screen 9 isinserted underneath the sash in the usual manner. T he de vice is thenplaced in position so that the lower extremity of the section 13 restson top or the raised lower sash, while the upper end of the section 12is directly below the underside of the top of the window casing. Thedevice is preferably inserted in such relative position to the windowpane 9 that either the end of the arm 26 of the sliding collar 25 or theinner edge of the adjustable locinng member 28 mounted on said arm bearslightl against the said pane. By adjusting the nut 22 the upper andlower secticns 12 and 13 are forced apart until the device is firmlyheld between the top of the lower sash and the underside of the top ofthe window casing. The sliding collar 25 is then adjusted vertically onthe upper secticn so that the locking member mounted on its arm 26 isdirectly underneath and in contact with the bottom face of the top railof the upper sash 7. As the locking mem-,

her is screwed upon the extension arm any desired adjustment thereofnecessary to insure a, proper bearing against the top sash rail can bereadily had. In the metallic embodiment of the device the operation isthe same except that additional adjustment can be had by moving thesection 30 relatively to the bolt as aforementioned.

When the adjustable collar has been moved intoproper position underneathand abutting against the upper sash rail, it is secured in place by theset screw 27, which can be readily tightened. Both the upper and lowersashes and the screen will thus be locked securely in place so that theycannot be moved until the device is detached, and this can only be donefrom the inside of the window. When it is desired to unlock and detachthe device in order to re-' move the screen or change the position ofthe sashes, the ad usting nut 18 unscrewed,

which draws the rod sections closer together and shortens the device sothat it can be readily removed from the window without in any wayinjuring the wood-work of the sashes or casing. In the metallicembodiment ofthe device such vertical shortening and lengthening of thedevice can be accomplished if desired, by turning the entire uppersection relative to the bolt.

If it is desired to use the fastener with the upper window sash loweredand a screen in place in the upper window space, the device is placed inposition so that its lower extremity rests on top of the lower sash andthe adjustable locking member is directly underneath and in contact withthe bottom .face of the top rail of the upper sash. Proper adjustment issecured by means of the adjusting nut.
